Donor and recipient contribution to phenotypic traits and the expression of biomineralisation genes in the pearl oyster model Pinctada margaritifera [PDF]

Scientific Reports, 2017
Grafting associates two distinct genotypes, each of which maintains its own genetic identity throughout the life of the grafted organism. Grafting technology is well documented in the plant kingdom, but much less so in animals. The pearl oyster, Pinctada

Combining population genomics, larval dispersal modelling and graph theory to reveal connectivity patterns of the black-lipped pearl oyster in French Polynesia [PDF]

Scientific Reports
Unravelling the mechanisms driving marine connectivity in open ocean environments remains a challenge, particularly for bentho-pelagic species, where larval dispersal further complicates analysis.

Leucettamine B and nacryline derivative promote the first steps of endochondral ossification in vitro [PDF]

Scientific Reports
Nowadays, there is a lack of pharmacological interventions designed to stimulate endochondral ossification (EO) in long bone fracture healing. In the search for new active compounds, marine organisms, particularly calcarea sponges and pearl oysters were ...

The plate collector, a new option for Pinctada margaritifera spat collection in French Polynesia

Aquaculture Reports, 2022
The aquaculture industry can constitute an important source of waste in the environment. In atoll lagoons of French Polynesia, among the materials used by pearl farmers, shade-mesh collectors can release toxic substances and are responsible of ...

Determination of Gender in the Pearl OysterPinctada margaritifera [PDF]

Journal of Shellfish Research, 2011
The pearl industry in French Polynesia is based on exploitation of natural stocks of the blacklip pearl oyster (Pinctada margaritifera). It generates an annual turnover of €90 million. Improvements in pearl quality need genetic studies to improve the populations.

Improved ocean-based nursery culture of blacklip pearl oyster (Pinctada margaritifera) juveniles in mesh baskets using cyanoacrylate adhesive

Aquaculture Reports, 2022
The blacklip pearl oyster, Pinctada margaritifera, supports well-established cultured pearl industries throughout the Pacific with various nursery culture methods used to on-grow juvenile oysters to a size suitable for pearl production. Locally-available

Insights from tyrosinase into the impacts of modified morphology of calcium carbonate on the nacre formation of pearl oysters

Frontiers in Marine Science, 2022
Tyrosinase is a type-3 copper protein with six conserved histidine residues within the copper-binding sites. It participates in mollusk nacre formation.

Influence of temperature and pearl rotation on biomineralization in the pearl oyster Pinctada margaritifera [PDF]

Journal of Experimental Biology, 2018
The objective of this study was to observe the impact of temperature on pearl formation using an integrative approach describing the rotation of the pearls, the rate of nacre deposition, the thickness of the aragonite tablets and the biomineralizing potential of the pearl sac tissue though the expression level of some key genes.

Sustainability and traceability in marine cultured pearl production [PDF]

, 2014
For centuries, wild pearl oysters and mussels were fished in the quest for natural pearls and shell material. This eventually led to the drastic overexploitation of oyster stocks in many areas of the globe.

Feeding the pearl oysterPinctada margaritiferaduring reproductive conditioning [PDF]

Aquaculture Research, 2011
This study aimed to model the food intake of P. margaritifera in order to examine the relationship between food level and reproductive activity. The effect of microalgae concentration on ingestion rate and assimilation efficiency was studied over a broad concentration range, using a mixture of Isochrysis galbana and Chaetoceros gracilis.
